Practice Questions

What are evolutionary changes in computing system?

centralized computing to parallel distributed and cloud computing

What is parallel computing?

either tightly coupled with centralized memory or loosely coupled with distributed memory

what is distributed computing ?

multiple autonomous computers, each having its own

private memory, communicating through a computer

network.

How Cloud computing is related to other computing models

resources can be either a centralized or a distributed computing system. The cloud applies parallel or distributed computing, or both. Clouds can be built with physical or virtualized resource

what are different computing models

Grid Computing Autonomic Computing Utility Computing

What Is facility of a Data Center

Email and file sharing

Productivity applications

Customer relationship management (CRM)

Enterprise resource planning (ERP) and databases

Big data, artificial intelligence, and machine learning

Virtual desktops, communications and collaboration services

what is Big data

Big data is a combination of structured, semi structured

and unstructured data collected by organizations. Used in machine learning projects, predictive modeling and other advanced analytic applications.

What is Cloud computing vision

Cloud computing provisions virtual hardware, runtime environments,

and services. These are used for as long as needed, with no up-front

commitments required. The entire stack of a computing system is transformed into a collection of utilities.

Define a cloud

Cloud computing refers to both the applications delivered as

services over the Internet and the hardware, system software in the

data centers that provide those services.

U.S. National Institute of Standards and Technology (NIST): Cloud

computing is a model for enabling ubiquitous, convenient, on-

demand network access to a shared pool of configurable computing

resources (e.g., networks, servers, storage, applications, and

services) that can be rapidly provisioned and released with minimal

management effort or service provider interaction.

Who are benefited

Cloud computing allows renting infrastructure, runtime environments, and services on a pay-per-use basis.

• IT officers of large enterprises see opportunities for scaling their

infrastructure on demand and sizing it according to their business needs.

• End users leveraging cloud computing services can access

their documents and data anytime, anywhere, and from any

device connected to the Internet.
